NASA Scientists send a small population of dogs to a new planet in order to test if it will be hospitable for human colonization. Through a random lottery, only Great Dane and St. Bernard dog breeds are sent, and the resulting population consists of tall, longhaired dogs. After 100 years these dogs return to Earth and are no longer able to mate with Earth dogs. This scenario is an example of
A. allopatric speciation through genetic drift. B. allopatric speciation through natural selection. C. sympatric speciation through genetic drift. D. sympatric speciation through natural selection.

Synthetic biologists are trying to create cells from raw material. One step in the process is encapsulating genetic material into a compartment. Researchers of the origin of life think that the earliest cells on Earth may have used RNA as their genetic material instead of DNA. As biologists consider which genetic material to use in creating their synthetic cells, which of the following characteristics of a single-stranded RNA genome should they keep in mind?
A. RNA is highly chemically stable relative to DNA. B. RNA cannot serve as a template. C. No enzymes can produce RNA. D. A newly synthesized RNA strand is not identical to the template strand.
